SHIPS TABLE.

Specification of Letters Patent.

Patented Feb.' 24, 1914.

Application filed October 6, 1913. Serial No. 793,638.

To all whom it may concern:

Be it known that I, JOHN ZsILAvETz, a subject of the King of Hungary,residing at South Bethlehem, in the county of North ampton and State ofPennsylvania,have invented certain new and useful Improvements in ShipsTables, of which the following is a specification.

This invent-ion relates generally to tables, and particularly to oneadapted for use upon sailing or steam vessels.

The object of the invention is, in already and practical manner, so tosupport the table from the deck or Hoor as to cause it always andautomatically to maintain a horizont-al position irrespective of theslant or angle assumed by the deck due to the action of the waves.

IVith the above and other objects in view, as will appear as the natureof the invention is better understood, the same consists in the novelarrangement and combination of parts of a self-leveling table, as willbe hereinafter fully described and claimed.

In the accompanying drawing, forming a part of this specification and inwhich like characters of reference indicate corresponding parts: Figure1 is a view in vertical longitudinal section through a self-levelingtable constructed in accordance with the present invention. Fig. 2 is ahorizontal section taken on the line 22, Fig. 1, and looking in thedirection of the arrows thereon. Fig. 3 is an enlarged fragmentarydetail view, partly in section, showin@ the manner in which the legs ofthe tablle are cushioned. Fig. 4 is a transverse sectional View taken onthe line 4-i, Fig. 1, and looking in the direction of the arrowsthereon. a sectional detail view, on an enlarged scale of a part of theapparatus.

Referring to the drawings, 1 designate the top of the table, 2 one ofthe sides there of, 3 the ends, and 4 the legs. These parts may be ofthe usual or any preferred construction and therefore need no furtherdescription.

Secured in any suitable manner to the deck or floor B are four cylindersor tubes 5, each housing a coiled spring 6, the lower whirl of each ofwhich bears upon the bottom 7 of the cylinder, the upper whirl beingengaged by an ovoidal shaped plunger head 8, one of which is carried byeach of the legs, and is of suiiiciently less diameter than the bore ofthe cylinder to permit the table Fig. 5 iSv -a sheave 21 and 22respectively.

to meet any angular spacing without any binding action occurring betweenthe head and the cylinder.` Secured to the under side of the table topis an eye bolt or hanger 9 that is engaged by one end of a link 10, theother end of which engages with an eye-bolt 11 carried by a boxing 12 inwhich are disposed a plurality of balls 13 that are normally spacedapart asuflicient distance to permit free Vrolling action, the boX,counterweights 18, and link 10 forming in effect a poising device.Secured to the under side of the box adjacent to each end is an eyebolt14 and 15 respectively, and secured in a bracket 16 arranged below thecenter .of the box is a grooved sheave 17, the sheave being providedwith two grooves that are separated by a peripheral flange 18.` Se curedto the deck or floor are two other standards 19 and 20, each of whichcarries The sheaves 17, 21, and 22, are engaged by ropes or chains 23and 24, the rope 23 having one end secured in the eye-bolt or hanger 14,thence turned once around the sheave 17 toward the left hand, thencepassed around` the sheave 21 and has its free end secured to an eye boltor a hanger 25 secured to the under side of the table top adjacent oneend. The rope 21 has one end secured in the eyebolt or hanger 15, thenceturned once around the sheave 17 toward the right hand,

vthence passed around the sheave 22, and has its free end secured to aneye bolt 26 secured to the under side of the table top adjacent to theend opposite the eye bolt 25.

From the construction described, it will be seen that as the vesselrolls, the weight box will be swung by the vessels motion, and thusoperate on either of the ropes or cables 23 or 24 to correct theinclination of the table and restore it and maintain it in a horizontalplane, the springs 6 in the cylinders 5 serving to cushion the table, sothat there will be no jars or vibrations present, no matter howviolently the vessel may be rocked.

In order to meet every contingency that might arise, say where a sea ofunusual roughness is encountered, and to prevent dangerous tilting ofthe table, supplemental Vchecking means are provided which consists offour chains 27 and 28, each of these chains being secured at one end toan eye bolt 29 and 30 respectively secured to the deck, and at theirother ends to eye-bolts 31 y vadjacent thev upper ends, the intermediateYby Letters Patent is and 32 secured to the inner sides of the legs fportion of the chains being passed beneath vgrooved sheaves 38 supportedby standards 34 secured to the deck. Normally, the chains are'out ofengagement with the sheaves 33, and only contact therewith ivlien thevessel makes an unusually heavy liirch, and one which would tend ormight tend to render the coaction between the legs and the cushioningsprings non-etlective.

" From the foregoing description it is' seen that; although theimprovements of the present invention' are simple in character,theyfivill be thorough-ly etiicient in securing 3 the Vobject sought,and wherein, further, by the' manner of V,arrangement Aot the. parts,

liability of derangement in use, is reduced to i the minimum.
